Design system for Figma plugin

There is one in Svelte: GitHub - thomas-lowry/figma-plugin-ds-svelte: Figma Plugin DS components made with Svelte
In React: GitHub - alexandrtovmach/react-figma-plugin-ds: React components of Figma design system
In Vue: GitHub - alexwidua/figma-plugin-ds-vue: 📚 Vue component library that matches the Figma Design System for building Figma plugins.

I don’t think there is anything for Bootstrap. (Can you even use it in plugins?)

Thanks for the links! It looks like they are based on this repo GitHub - thomas-lowry/figma-plugin-ds: A small lightweight design system for use in Figma Plugins. I played with it a bit and it looks a bit unclear for me… e.g. why icon button has different border radius from regular button, or why all buttons have display: flex. I thought maybe Figma has kind of solid solution (including custom components) to make all plugins look a bit more native way.
I used bootstrap in plugins several times, it’s more about packing it. Maybe it worth playing with its customization to make it look more native.
